Physics: damping% & Angular damping limit?

For questions about using Classic.

Post » Mon Aug 10, 2009 10:17 pm

I have two questions pertaining to the physics behavior.

1: The linear and angular damping fields are measured as percentiles. What is the damping value a percent of? (e.g. If the value is set to 100, it is displayed as 100%, but 100% of what?)

2: While the "Linear damping" field can be set to values far in excess of 100% (e.g. 5000%), the "Angular damping" cannot be set higher than 100%. Am I overlooking an option that would allow for higher angular damping values, or is this a built-in limitation?

Thanks.

It's a limitation of the Box2D physics engine that we use (I'm not sure what units it uses). You can create a higher angular damping by applying an opposite proportional torque.

Thanks. That was the workaround I was using. I just wanted to be sure I wasn't missing something. Thanks again. :)
